Explanation:
There are five (5) main forms of encryption: <em>Electronic Code Book (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Output Feedback (OFB)</em>. Electronic Code Book (ECB) is the simplest of all of them. Using this method to encrypt information implies dividing a message into two parts to encrypt each block independently. ECB does not hide patterns effectively because the blocks are encrypted using identical plaintexts.
